Description

Technical Field

[0001] This invention relates to the field of communication network equipment technology, and in particular to an outdoor optical modem cabinet. Background Technology

[0002] An optical modem is a transceiver device that converts optical Ethernet signals into other protocol signals. Also known as a single-port optical transceiver, it is a product designed for specific user environments. It uses a pair of optical fibers to perform point-to-point optical transmission terminal equipment with a single E1, a single V.35, or a single 10BaseT.

[0003] Optical modems (ONMs) utilize large-scale integrated chips, resulting in simple circuitry, high reliability, and comprehensive alarm status indication and network management functions. However, existing outdoor racks for placing OMMs have several drawbacks: 1. While some racks have cooling functions, in situations where external power is sometimes scarce outdoors, they may not be able to adequately power the cooling system while simultaneously supplying power to the OMMs and adapters inside; 2. In traditional racks, operators typically select different numbers of OMMs and adapters to house them based on user needs, but this requires prolonged operation. The high heat generated during operation leads to high temperatures for the optical modem, making it susceptible to burnout. Furthermore, the number of optical modems and adapters is not individually configured, requiring careful planning of the cabinet's interior to ensure neat and orderly placement. Thirdly, while existing cabinet cooling systems don't consider power sufficiency when power is ample, in outdoor environments with limited external power, power availability significantly impacts cooling efficiency. We propose an outdoor optical modem cabinet to maximize cooling efficiency within limited power conditions, based on the number of optical modems and adapters installed. Summary of the Invention

However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example 1

[0030] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides an outdoor optical modem cabinet. The outdoor optical modem cabinet includes a cabinet 1, a support component 2, an optical modem component 3, an adapter component 4, and a heat dissipation mechanism 5. The support component 2 is used to install the optical modem component 3 and the adapter component 4 in an orderly manner. The heat dissipation mechanism 5 can achieve maximum heat dissipation efficiency under limited power conditions.

[0031] Specifically, the outdoor optical modem cabinet includes a cabinet 1, a support assembly 2, an optical modem assembly 3, an adapter assembly 4, and a heat dissipation mechanism 5. A cabinet door 1a is hinged to the front opening of the cabinet 1. An air inlet 1b is located in the middle of the bottom wall of the cabinet 1, and a mesh cover 1c is installed at the bottom of the air inlet 1b. A solar panel 1d is installed at the top of the cabinet 1. A battery 1e and an inverter 1f are installed on the inner wall of the cabinet door 1a. The support assembly 2 includes three sets of support members spaced apart inside the cabinet 1. Each set of support members includes two uprights 2, one on the front and one on the back of the cabinet 1. a. The column 2a has mounting holes 2a-1 evenly spaced along its length; the optical modem assembly 3 and the adapter assembly 4 are fixedly connected to the mounting holes 2a-1 by fasteners; the heat dissipation mechanism 5 includes a rotating motor 5a located at the top of the mesh cover 1c; the output end of the rotating motor 5a is provided with a first cylindrical gear 5a-1; the end of the first cylindrical gear 5a-1 is provided with a first impeller 5a-2; the solar panel 1d and the rotating motor 5a are electrically connected to the battery 1e respectively; and the inverter 1f is electrically connected to the adapter assembly 4 and the external power supply respectively.

[0032] The solar panel 1d absorbs light energy outdoors and converts it into electrical energy, which is stored in the battery 1e. The battery 1e provides power to the rotating motor 5a. The rotating motor 5a drives the first impeller 5a-2 to rotate. The fan blades on the first impeller 5a-2 drive the external air into the cabinet through the air inlet 1b and remove the heat inside the cabinet.

[0033] Preferably, the heat dissipation mechanism 5 further includes two first rotating columns 5b rotatably disposed on both sides of the bottom wall of the cabinet 1. A second cylindrical gear 5b-1 is disposed at the top of the first rotating column 5b, and a first bevel gear 5b-2 is disposed at the top of the second cylindrical gear 5b-1. The second cylindrical gear 5b-1 and the first cylindrical gear 5a-1 are connected by a first chain 5c.

[0034] When the rotating motor 5a rotates, the rotating motor 5a drives the second cylindrical gears 5b-1 on both sides of the bottom wall of the cabinet 1 to rotate through the first cylindrical gear 5a-1 and the first chain 5c. The second cylindrical gears 5b-1 drive the first bevel gear 5b-2 to rotate.

[0035] Preferably, the two side walls of the cabinet 1 are provided with a first ventilation hole 1g, a second ventilation hole 1h, and a third ventilation hole 1i from top to bottom in the middle. A rain cover 1j is provided on the outside of the first ventilation hole 1g, the second ventilation hole 1h, and the third ventilation hole 1i. A first guide rail 1g-1 and a second guide rail 1h-1 are horizontally placed at the first ventilation hole 1g and the second ventilation hole 1h. A second rotating column 5d is rotatably arranged on the lower side of the middle of the third ventilation hole 1i. A third cylindrical gear 5d-1 is provided at one end of the second rotating column 5d. A second bevel gear 5d-2 that meshes with the first bevel gear 5b-2 is provided at the end of the third cylindrical gear 5d-1.

[0036] The rain cover 1j can prevent rainwater from entering the cabinet 1 through the first ventilation hole 1g, the second ventilation hole 1h, and the third ventilation hole 1i when it rains. When the rotating motor 5a drives the first bevel gear 5b-2 to rotate, the first bevel gear 5b-2 meshes with the second bevel gear 5d-2, so the first bevel gear 5b-2 drives the second bevel gear 5d-2 to rotate.

[0037] Preferably, a support frame 5e is fixed on the side of the third ventilation hole 1i. A first bearing 5e-1 is provided in the middle of the support frame 5e. A first rotating rod 5e-2 is fixed in the inner ring of the first bearing 5e-1. A fourth cylindrical gear 5e-3 and a second impeller 5e-4 are arranged sequentially on the outer wall of the first rotating rod 5e-2 facing the third ventilation hole 1i. Several fan blades are evenly distributed on the second impeller 5e-4. The other end of the first rotating rod 5e-2 is connected to the first gear ring 5e-6 through the first connecting plate 5e-5. The fourth cylindrical gear 5e-3 and the third cylindrical gear 5d-1 are connected by a second chain 5e-7.

[0038] When the second bevel gear 5d-2 rotates, it drives the fourth cylindrical gear 5e-3 to rotate through the third cylindrical gear 5d-1 and the second chain 5e-7. The fourth cylindrical gear 5e-3 then drives the first rotating rod 5e-2 to rotate in the first bearing 5e-1, which in turn drives the second impeller 5e-4 to rotate, thus expelling the internal heat from the cabinet through the third ventilation hole 1i.

[0039] Preferably, a magnet is embedded inside the second guide rail 1h-1 at a position corresponding to the first rotating rod 5e-2. A second bearing 5f is slidably engaged inside the second guide rail 1h-1. A second rotating rod 5f-1 is fixed in the inner ring of the second bearing 5f. A third impeller 5f-2 is provided on the outer wall of the second rotating rod 5f-1. Several fan blades are evenly distributed on the third impeller 5f-2. The end of the second rotating rod 5f-1 is connected to the second toothed ring 5f-5 through the second connecting plate 5f-4. When the second toothed ring 5f-5 is located directly above the first toothed ring 5e-6, the second toothed ring 5f-5 and the first toothed ring 5e-6 mesh with each other.

[0040] When there are many optical modems or adapters corresponding to the position of the second ventilation hole 1h, a lot of heat is generated. At this time, move the second rotating rod 5f-1 until the second bearing 5f is fixed by the magnetic force of the magnet in the second guide rail 1h-1. At this time, the second toothed ring 5f-5 and the first toothed ring 5e-6 are just engaged. Driven by the first toothed ring 5e-6, the second toothed ring 5f-5 also begins to rotate. When the second toothed ring 5f-5 rotates, it drives the third impeller 5f-2 on the second rotating rod 5f-1 to rotate. The added third impeller 5f-2 can speed up the discharge of heat from the cabinet to the outside of the cabinet.

[0041] Preferably, a magnet is embedded inside the first guide rail 1g-1 at a position corresponding to the first rotating rod 5e-2. A third bearing 5g is slidably arranged inside the first guide rail 1g-1. A third rotating rod 5g-1 is fixed in the inner ring of the third bearing 5g. A fourth impeller 5g-2 is arranged on the outer wall of the third rotating rod 5g-1. Several fan blades are evenly distributed on the fourth impeller 5g-2. The end of the third rotating rod 5g-1 is connected to the third toothed ring 5g-5 through the third connecting plate 5g-4. When the third toothed ring 5g-5 is located directly above the first toothed ring 5e-6, the third toothed ring 5g-5 meshes with the second toothed ring 5f-5.

[0042] When there are many optical modems or adapters corresponding to the position of the first ventilation hole 1g, more heat is generated. At this time, the third rotating rod 5g-1 is moved until the third bearing 5g is fixed by the magnetic force of the magnet in the first guide rail 1g-1. At this time, the third toothed ring 5g-5 and the second toothed ring 5f-5 are just engaged. Driven by the second toothed ring 5f-5, the third toothed ring 5g-5 rotates, which drives the fourth impeller 5g-2 on the third rotating rod 5g-1 to rotate. The added fourth impeller 5g-2 can speed up the discharge of heat from the cabinet to the outside of the cabinet.

[0043] During use, the optical modem assembly 3 and adapter assembly 4 are fixedly connected to the mounting holes 2a-1 on the column 2a using fasteners. The operator observes the number of optical modem devices and adapters at the positions corresponding to the first ventilation hole 1g and the second ventilation hole 1h. When the number of optical modem devices and adapters at the positions corresponding to the first ventilation hole 1g and the second ventilation hole 1h is large, it is necessary to exhaust the heat inside the cabinet through the first ventilation hole 1g and the second ventilation hole 1h. Move the second rotating rod 5f-1 until the second bearing 5f is fixed by the magnetic force of the magnet inside the second guide rail 1h-1. At this time, the second gear ring 5f-5 and the first gear ring 5e-6 are just engaged. The third impeller 5f- on the second rotating rod 5f-1... 2. Facing the second ventilation hole 1h, move the third rotating rod 5g-1 until the third bearing 5g is fixed by the magnetic force of the magnet inside the first guide rail 1g-1. At this time, the third gear ring 5g-5 and the second gear ring 5f-5 are just meshed. The fourth impeller 5g-2 on the third rotating rod 5g-1 is facing the first ventilation hole 1g. Turn on the rotating motor 5a. The rotating motor 5a drives the first impeller 5a-2 to rotate. The fan blades on the first impeller 5a-2 drive the external air into the cabinet through the air inlet 1b to cool the optical modem component 3 and the adapter component 4. The rotating motor 5a drives the second cylindrical gear 5b-1 on both sides of the bottom wall of the cabinet 1 to rotate through the first cylindrical gear 5a-1 and the first chain 5c. Gear 5b-1 drives the rotation of the first bevel gear 5b-2. Since the first bevel gear 5b-2 meshes with the second bevel gear 5d-2, the first bevel gear 5b-2 drives the second bevel gear 5d-2 to rotate. When the second bevel gear 5d-2 rotates, it drives the rotation of the fourth cylindrical gear 5e-3 through the third cylindrical gear 5d-1 and the second chain 5e-7. The fourth cylindrical gear 5e-3 then drives the first rotating rod 5e-2 to rotate within the first bearing 5e-1, which in turn drives the rotation of the second impeller 5e-4, expelling internal heat from the cabinet through the third ventilation hole 1i. The rotation of the first rotating rod 5e-2 drives the rotation of the first gear ring 5e-6, which in turn drives the rotation of the second gear ring 5f-5. This, in turn, drives the rotation of the third impeller 5f-2 on the second rotating rod 5f-1. The third impeller 5f-2 discharges hot air through the second ventilation hole 1h. The rotation of the second gear ring 5f-5 also drives the rotation of the third gear ring 5g-5. The third gear ring 5g-5 then drives the rotation of the fourth impeller 5g-2 on the third rotating rod 5g-1. The fourth impeller 5g-2 discharges hot air out of the cabinet through the first ventilation hole 1g. When the number of optical modem devices and adapters corresponding to the first ventilation hole 1g or the second ventilation hole 1h is small, the fourth impeller 5g-2 can be moved next to the first ventilation hole 1g by sliding the third bearing 5g, and then the third impeller 5f-2 can be moved next to the second ventilation hole 1h by sliding the second bearing 5f.Therefore, the operation of the third impeller 5f-2 and the fourth impeller 5g-2 can be adjusted according to the number of optical modem devices and adapters. In outdoor environments with limited power, this achieves energy saving while maximizing heat dissipation efficiency. Example 2

When the number of optical modem devices and adapters corresponding to the positions of the first ventilation hole 1g and the second ventilation hole 1h is large, it is necessary to exhaust the heat inside the cabinet through the first ventilation hole 1g and the second ventilation hole 1h. Move the second rotating rod 5f-1 until the second bearing 5f is fixed under the magnetic force of the magnet in the second guide rail 1h-1. At this time, the second gear ring 5f-5 and the first gear ring 5e-6 are just meshed. The third impeller 5f-2 on the second rotating rod 5f-1 is facing the second ventilation hole 1h. Move the third rotating rod 5g-1 until the third bearing 5g is fixed under the magnetic force of the magnet in the first guide rail 1g-1. At this time, the third gear ring 5g- 5 meshes with the second gear ring 5f-5. The fourth impeller 5g-2 on the third rotating rod 5g-1 is directly opposite the first ventilation hole 1g. The rotating motor 5a is turned on, which drives the first impeller 5a-2 to rotate. The fan blades on the first impeller 5a-2 drive external air into the cabinet through the air inlet 1b to cool the optical modem assembly 3 and the adapter assembly 4. The rotating motor 5a drives the second cylindrical gears 5b-1 on both sides of the bottom wall of the cabinet 1 to rotate through the first cylindrical gear 5a-1 and the first chain 5c. The second cylindrical gears 5b-1 drive the first bevel gear 5b-2 to rotate. Since the first bevel gear 5b-2 meshes with the second bevel gear 5d-2, the first bevel gear 5b-2 drives the second bevel gear 5d-2 to rotate.When the second bevel gear 5d-2 rotates, it drives the fourth cylindrical gear 5e-3 to rotate via the third cylindrical gear 5d-1 and the second chain 5e-7. The fourth cylindrical gear 5e-3 then drives the first rotating rod 5e-2 to rotate within the first bearing 5e-1, which in turn drives the second impeller 5e-4 to rotate, expelling internal heat from the cabinet through the third ventilation hole 1i. The rotation of the first rotating rod 5e-2 drives the rotation of the first gear ring 5e-6, which in turn drives the rotation of the second gear ring 5f-5, which in turn drives the rotation of the third impeller 5f-2 on the second rotating rod 5f-1. The third impeller 5f-2 expels hot air through the second ventilation hole 1h. The rotation of the second gear ring 5f-5 also drives the rotation of the third gear ring 5g-5. The third gear ring 5g-5 then drives the rotation of the fourth impeller 5g-2 on the third rotating rod 5g-1. The fourth impeller 5g-2 exhausts hot air from the cabinet through the first ventilation hole 1g. When the number of optical modem devices and adapters corresponding to the first ventilation hole 1g or the second ventilation hole 1h is small, the fourth impeller 5g-2 can be moved next to the first ventilation hole 1g by sliding the third bearing 5g, and then the third impeller 5f-2 can be moved next to the second ventilation hole 1h by sliding the second bearing 5f. Therefore, the operation of the third impeller 5f-2 and the fourth impeller 5g-2 can be adjusted according to the number of optical modem devices and adapters. In outdoor environments with limited power, this can achieve energy saving while maximizing heat dissipation efficiency.
